Transient neonatal hypothyroidism following a short course of maternal amiodarone therapy

Background: Amiodarone is an iodine-rich medication used to treat maternal and fetal arrhythmias, with known effects on thyroid hormone homeostasis. Case presentation: We describe a case of transient neonatal hypothyroidism following a short prenatal course of maternal amiodarone therapy resulting in neonatal TSH elevations exceeding those reported in the available literature.
